@object-ui/core evaluatePlainCondition still reads a bare-string predicate on the legacy JS grammar after #27457

domain:ui#1 · os-sales · session_01L6bhgXU26UBEjd1KKHgNEx

Filing gate: ② a declared-vs-enforced gap on a published export, found by the contract review of PR #27584 (#27457), record 6499697983 should-fix 3.
Business reason: after #27584 the console reads every bare-string predicate as CEL, the way @objectstack/spec defines it and the server reads it. evaluatePlainCondition, still exported from the published @object-ui/core, keeps reading a bare string on the legacy JavaScript grammar (===, ?., .includes( …), and its own tests pin that. No console caller uses it today, but any host or plugin that calls it gets the opposite dialect from every other predicate path, silently.
Reader who acts: the triage seat (first grading: align it to CEL, or retire the export), then domain:ui.
Dedupe words: evaluatePlainCondition bare string JS grammar, plain condition legacy dialect.

Mechanism

ui/packages/core/src/evaluator/ evaluatePlainCondition (published export) evaluates a bare string on the legacy grammar; ExpressionEvaluator.evaluateCondition routes the same string to CEL after fix(ui-core): read a bare-string predicate as CEL shorthand, as the spec and server do #27584.
Its tests pin ===.
Spec: packages/spec/src/shared/expression.zod.ts transforms a bare string to { dialect: 'cel', source }.

⛔ Not a claim.

Read fresh. Graded as align, not retire: @objectstack/spec defines a bare-string predicate as CEL, and after fix(ui-core): read a bare-string predicate as CEL shorthand, as the spec and server do #27584 every other console path reads it that way. evaluatePlainCondition routes a bare string to the same CEL evaluator. Its === pins are rewritten to the CEL spelling on purpose, and the changeset states the dialect change for hosts that call the export.
Retiring a published export is a removal and is not graded here.

Clause-②: no (narrowing) — a bare string handed to the published evaluatePlainCondition is read as CEL, so a JS-only spelling (===, .includes() it accepted before is refused; the seat owes a CONTRACT_REVIEW_TIER review before the queue (precedent #27584, review 6499697983)

Fault policy kept: a CEL fault throws into the existing catch and answers false, a non-boolean result answers false, a blank or non-string condition answers false by an explicit guard (evaluateCondition would answer a blank gate true). The JS-grammar compound pin is rewritten to the CEL spelling; new pins cover CEL-only constructs, JS-only spellings refused with false beside their CEL controls (no console line), bare data.field, parity with evaluateCondition over six pairs, template unchanged, blank false.
